Limitations and Bugs in Some Types of SPSS Graphs

SPSS graphing routines are very powerful. For example, they can automatically generate error bars showing 95% confidence intervals--for means as well as for frequencies. However, as of 2020 there were various bugs and other limitations plaguing SPSS graphs. Because these problems have persisted for so long, it would be wise to seek out other options for producing graphs. As of 2020, options were limited.

R can produce good graphs, but the process of writing GGPlot2 scripts to produce the graphs can be arduous. Richard Anderson has created an R script for producing a particular type of high-information graph that's appropriate to many circumstances. See R Scripts .

As of 2020 jamovi did not yet offer editable graphs (it's crucial to be able to edit the range of an axis). Another, online option for some specialized types of graphs is SuperPlotsOfData.

SpoonFlower Fabric Posters

SpoonFlower is in the business of producing custom printed fabrics. But the company also offers a not-widely-known service for printing a $20.00-to-$40.00 cloth research poster (typically, posters cost much more). The advantage of cloth is that it's foldable and thus easy for you to transport).
You can choose the type of fabric in which to print the poster. Spoonflower recommends "Performance Pique," for its wrinkle resistance. However, Performance Pique is stretchy, typically resulting in a hung poster that is weirdly stretched/distorted. For this reason, I recommend a cotton fabric such Petal Signature Cotton. It's a little more expensive, but it's wider, and a lot less stretchy (and probably better for the environment too). There will be wrinkles and creases but your conference hotel room will likely include a clothes iron that you can use to remove major wrinkles. In my opinion, a few wrinkles is better than a hung poster that's stretched/distorted.
I recommend LibreOffice Draw, rather than Microsoft PowerPoint, as the most trouble-free tool for creating a poster. This is because PowerPoint doesn't do a good job permitting the user to control the dots-per-inch resolution. Also, each dimension of a PowerPoint slide may not exceed 50 inches.
For a roughly 8 by 4 foot poster, start by configuring a LibreOffice Draw page to 72" wide by 42" long (not 48" because Petal Signature Cotton is only 42" wide). Note that later you'll rotate the finished image by 90 degrees before sending it to be printed.
For a poster that's no wider than 42", configure the LibreOffice Draw page to 42" wide by 36" long. (In this case, no rotation will be required before printing). It will help, later on, if your poster design includes a surrounding rectangle (you can use this a visual guide for trimming the fabric, with scissors).
You want to avoid working with raster (pixel-based) images when possible, since they can't be enlarged without loss of quality.
While SVG is a nice, modern vector graphics format, it sometimes becomes misformatted. Thus, I recommend that if you paste and svg into Draw, you subsequently "convert" it to "metafile" format.
Once you're satisfied with how the poster looks in Draw, export it as a 150 dpi PNG image (and be sure to readjust the width and height after changing the dpi setting).
Once you've created your 150-dpi PNG, go to http://www.spoonflower.com/designs/new?create=fabric and upload your image: Select REPEAT CENTER.
At this point you should select SAVE CHANGES.
Only after saving should you select: PETAL SIGNATURE COTTON; YARDS, and then select a number of yards that gives you a complete poster. Do NOT select 'Save changes' again.
Select ADD TO CART.
